Sorry but you are wrong, the Xpro1 is more than 10mm wider than the Xt1. The Xt1 is about the same size as the XE, just a bit higher because of the hump for the finder which doesn`t help ergonomically. And there are quite big lenses on the roadmap! To me it is more comfortable to hold a body the size of the Xpro1 especially with bigger lenses attached. And I am not considering the Xpro1 as I am waiting for a Xpro2 which will hopefully be launched with at least the performance of the Xt1 plus OFV. Until then I will happily continue to use my S3pro.
